SPECIFICATION forming part of Letters Patent No. 513,412, dated January23, 1894.

Application led May 19,1393.

To all whom it may concern.-

Be it known that I, WILLIAM BIRT NEvILL, a citizen of the United States,residing at Rockwall, in the county of Rockwall and State of Texas, haveinvented a new and useful Ejector-Pump, of which the following is aspecification.

This invention relates to pumps; and it has for its obj ect to providecertain improvements in ejector pumps operated by air or steam pressure,whereby means shall be provided for easily lifting water to any suitableheight, and conducting the same any distance from the well.

To this end .the main and primary objects of the invention are toprovide certain improvements in pumps of the character noted, to secureeasy operation and practical efficiency.

With these and other objects in view which will readily appear as thenature of the invention is better understood, the same consists in thenovel construction, combination and arrangement of parts hereinaftermore fully described, illustrated and claimed.

In the accompanying drawingsz-Figure 1 is a perspective view of a pumpconstructed in accordance with this invention` Fig. 2 is an enlargedsectional view of the combined water and air cylinders showing theconnections of the water and air pipes therewith. Fig. 3 is an enlargeddetail sectional View of the air cylinder and the pumping devicestherein.

Referring to the accompanying drawings, A represents a combined waterand air cylinder arranged under the ground so as to be partly disposedin the water of the well from whichA the water is to be lifted, and saidcombined Water and air cylinder A, has detachably connected to the topend thereof the discharge pipe B, which pipe may be led by suitableconnections C, any distance above the cylinder A, and carried to anyconvenient point of use, near to or away from the well, and such pipe isof course of a size smaller than the diameter of the cylinder, butadapted to accommodate the full discharge of water from said cylinder.

The cylinder A, has detachably threaded into opposite sides thereof atan intermediate point the opposite water inlet pipes D, which Serial No.474,819. (No model.)

pipes open at their outer ends into the water of the well, and areprovided with the check valve E, which prevent back flow of the waterthrough such pipes, and detachably threaded into the lower end of thecylinder below the connections of the water inlet pipes therewith is theair or steam inlet pipe F. This pipe is provided with an inner ejectoror nozzle portion which projects inside of the cylinder to a point abovethe connection of the pipes D therewith, so as to create a powerfulsuction for drawing the water into the cyl- -inder through said pipes.

The air or steam inlet pipe F, which enters `the lower end of thecylinder A, is provided withl a check valve G, immediately below thecylinder, in order to prevent the water rising vin the air or steamconducting pipe H. The

air or steam conducting pipe H, rises to the to one end of the.horizontal air cylinder I. The horizontal air cylinder I, may of coursebe arranged in any suitable position inside of a house or otherconvenient point, and is preferably supported on the stand legs J. Theair cylinder I, is open at one end to accommodate the valved air plungerK, moving therein, which plunger has extended from one side thereof theplu nger rod L, moving through the perforated rod guide M, attached tothe open end of such cylinder. An operating link N, is pivotallyconnected at one end to the plunger rod L, and at its other end to thehandle lever O. lh" handle lever O, is pivoted at its lower end to thedepending leg bracket P, attached to the bottom side of the' aircylinder, and also serving as al support therefor. Now itwill beapparent that by manipulating the handle lever O, air is forced underpressure through the pipesH, and F, into the combined water and aircylinder A. The air entering'the cylinder A, under pressure, draws inthe water into such cylinder through the pipes D, and carries it upthrough the discharge pipe and to the point of use, thereby providingfor the quick elevation of water by simple and efficient means..

lf found desirable or convenient the handle lever O, may be dispensedwith and other suitable operating means connected withv the plunger, andit will also be understood that the same principle will be stillobserved if 5 steam is employed instead of air to maintain the necessarypressure to elevate the water, and in such case the pipe H, may beconnected with an ordinary steam boiler X, such as shown in dotted linesin Fig. 3, of the drawings, audin either use the pipe His also providedwith check valves Q, near its connection with the air pump or cylinderand the steam boiler, to prevent the return of air or steam.

The herein described ejector pump possesses several advantages overconstructions already patented, and it is to be noted that, by being ofa separable construction, the taking apart and setting up of the pumpparts is zo rendered very easy and convenient, and relative to theoperation of the puinp'it is to be noted that the enlarged cylinder A,renders the operation of the pump much more effective than theconstructions set up in previous patents, by reason of the fact that thesaid cylinder will not only accommodate a greater supply of water, butwill insure the powerful lift thereof through the smaller discharge pipeB, while in the patented constructions, 5o the supply of waterfrom theinlet pipes leads directly into the discharge pipe, and necessarilyrequires a suction or pressure of gas or air sufficient to lift theentire supply, which under all conditions is not practicable.

, Changes in the form, proportion and the minor details of constructionas embraced within the scope of the appended claimsmay be resorted towithout departing from the principle or sacrificing any of theadvantages 4o of this invention. i

Having thus described the invention, what is claimed, and desired to besecured by Letters Patent, is-

1. In a separable ejector pump, the combination of an enlarged water andair cylinder having threaded openings in its upper and lower ends, adischarge pipe detachably threaded into the threaded opening in the topof the cylinder, said discharge pipe being of a smaller diameter thanthe enlarged cylinder, separate and independent o-standing water inletpipes D, detachably threaded at one end into opposite sides of theenlarged cylinder at a point intermediate of its ends and having loweropen ends provided with check valves E, a valved air or steam pressurepipe having a threaded portion removably engaging the threaded openingin the lower end of the cylinder, and an inwardly extending ejectornozzle portion disposed above said threaded portion and projectinginside of the cylinder to a point above the connection of the pipes D,therewith, and a pump connected with said pressure pipe, substantiallyas set forth.

2. In a pump of the class described, the combination with the combinedwater and air discharge cylinder, and an air pipe connected therewith;of an open air cylinder connected with said air pipe and having standlegs one of which forms a pivot bracket, a valved plunger moving in saidopen cylinder, and the handle lever connected with said plunger andpivoted to said pivot bracket leg, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

WILLIAM BIRT NEvILL.
